14 Claims.

My invention relates to improvements in type casting machines and has for one object to provide a new and improved type casting machine adapted to be controlled for the selection of the characters to be cast by a commercial typewriter and wherein the arrangement of typewriter, matrices, matrix selecting mechanism, mold and pot for type metal is compact and convenient and provides an erect and durable construction.

In general my invention comprises an inclined matrix bed, the matrices in the inactive position being adapted to be contained in the upper end of the bed and being adapted to be fed downward to the casting position. The typewriter and the matrix selecting mechanism occupied by thetypewriter is located above the lower end of the inclined matrix bed with only somuch of the assembly including the typewriter projecting laterally beyond the vertical plane bounding the end of the matrix bed as is necessary to permit the operator to assume a comfortable position at the typewriter. The mold, the melting pot and the pot and mold and matrix driving and controlling mechanism is located beneath the matrix bed with substantially all of it contained behind a vertical plane bounding the upper end of the inclined matrix bed whereby the mechanisms especially including the mold are easily accessible.

My invention is illustrated more or less diagrammatically in the accompanying drawings, wherein Figure 1 is a diagrammatic side elevation with parts omitted;

Figure 2 is a front elevation;

Figure 3 is a rear elevation;

Figure 4 is an enlarged cross section taken on the line 4-4 of Figure 3.

Like parts are indicated by like characters throughout the specification and drawings.

A is a supporting base frame. Al is a matrix bed. It extends diagonally and rearwardly upward from the front corner of the base to a point substantially above the rear end of the base. A2 are matrix strips mounted for reciprocation in the matrix bed. These strips are normally in the upper position, that being the position of starting. A3 is a slot in the matrix bed intermediate its two ends. A4 is a mold adapted to cooperate with the matrix strips through said slot, the matrix strips forming one side of the mold whereby slugs may be cast. A5 is a pot having a spout A6 adaped to form a side of the mold opposed to the matrix strips. AT is a pump in the pot adapted to force molten metal from the pot through the spout into the mold to cast the slug. All this mechanism is located beneath the underside of the matrix bed and is contained within a triangle formed by the matrix bed, the frame and the vertical plane passing through the upper rear end of the matrix bed.

B is a matrix selecting mechanism. The elements of this selecting mechanism form no part of this invention, sufiice it to say, that the housing shown contains stub pins adapted to be thrust into the path of the matrix strips so that when the matrix strips are moved longitudinally, they engage these stub pins and being stopped at selected points, position selected characters on the matrix strips in register with the mold. Bl is a typewriter mounted above the lower end of the matrix bed and overhanging or projecting beyond the bed and frame only a distance sumcient to enable the operator to sit comfortably at the typewriter to operate it to cause operation of the matrix selecting means. The top of this typewriter is below the upper end of the matrix bed so that substantially all the machinery involved in the type selecting and casting operation except the typewriter itself is contained within a rectangle bound by two vertical planes extending through the upper and lower ends of the matrix bed and two intersecting horizontal planes ex tending through the upper and lower ends of the matrix bed.

I claim:

1. 111a type casting machine, an inclined matrix bed, matrix selecting and type casting mechanism associated therewith, a typewriter'adapted to control the operation of the matrix selecting mechanism, the matrix selecting and type casting mechanism being contained substantially within an area bounded by the two horizontal and two vertical planes which pass through the upper and lower ends of the matrix bed.
